This mystery writer, whose sales were second only to
Shakespeare, disappeared for 11 days in December 1926.
Who is Agatha Christie? The search could have been one of her
greatest mysteries. It involved hound dogs, 1,000 police officers,
countless civilians, a psychic, and—for the first time—airplanes. The
tabloid press had a field day weaving scenarios. On the 11th day, she
was found in a hotel with no memory of what happened.
